How to buy a better quality soft silicone phone case

<p>The material of the soft <a href="https://www.silicagelzrt.com/silicone-phone-case" rel="noopener noreferrer" target="_blank">silicone phone case</a>&nbsp;is a highly active adsorption material, which is an amorphous substance, and its chemical formula is mSiO2·nH2O. It is insoluble in water and any solvents, non-toxic, tasteless, chemically stable, and does not react with any substances except strong alkalis and hydrofluoric acid. The chemical composition and physical structure of silica gel determine that it has many other similar materials that are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.</p><p><br></p><p>The purchase of silicone sleeves should be distinguished from the following aspects:</p><p>1. Material: divided into pure silica gel and ordinary glue. Pure silica gel has good toughness and will not turn white when stretched hard, while ordinary silica gel is easy to break, and the rubber material will turn white when you pull it gently, indicating that there is a cheap added value Silicon powder is shoddy.</p><p>2. Hand feeling: good hand feeling is smooth, bad hand feeling sticky;</p><p>3. Appearance: good color is uniform, poor surface is rough, color is different, even impurities can be observed;</p><p>4. Taste: Silicone has a more or less peculiar smell. Poor silicone has a particularly strong and unpleasant smell.</p><p>5. Second, the mold is different. The reasonableness and precision of the mold design establish the quality and ease of use of the silicone sleeve.</p><p>6. Others, the thickness of the silicone rubber, post-processing, etc. will also affect the cost of the silicone sleeve.</p><p>Generally speaking, the thicker the silicone sleeve, the higher the cost. But it's not that thicker is better, or thinner is worse. For example, thicker ones may affect the feel/handling, thinner ones are more personal.</p><p>7. Post-processing, including dust-proof treatment, burr trimming, etc.</p><p><br></p><p><br></p>
